Anchorage system for guardrail

ABSTRACT

An anchorage system is provided for fixing the guardrail tubes for the building works. The anchorage system includes a body member having a recess, an end portion being formed thereof locations allowing to receive screws fitting therewith for be fixed in a wood casing before that the concrete be poured therein and that the casing be removed thereof, a cavity, and grooves. 
     The recess receives an end tube provided of a rod and being formed as integral part of a guardrail tube. The end tube is blocked therein the cavity by the rod sliding therein grooves, and for that the end tube be blocked therein, the guardrail tube is rotated and fixed to the braces. The same anchorage system is also used with a fastening device for connecting a safety harness in a concrete slab.

This is a continuation of the application No. 61/068,278. BACKGROUND OFTHE INVENTION

1. Field of the Invention

The present invention relates to an anchorage system conceived forfixing the guardrail tubes for the building works.

2. Description of the related art

A search of prior art records has unveiled the following patents:

-   -   CA 1,147,585 issued in 1983 to Sanchez Velasco;    -   U.S. Pat. No. 6,761,002 issued in 2004 to Sorkin;    -   U.S. Pat. No. 6,109,597 issued in 2000 to Sicking et al.; and    -   U.S. Pat. No. 4,037,384 issued in 1977 to Molyneux.

SUMMARY OF THE INVENTION

It can be deduced that the presently existing systems do not afford acomplete security and can cause loss of human life.

It is therefore an object of the invention to provide a new anchoragesystem which give a complete degree of safety, and which can be obtainedwith the system being discussed in the present disclosure. The anchoragesystem comprises a body member having an end portion being formedthereof locations allowing to receive screws fitting therewith for befixed in a wood casing before that the concrete be poured therein, andthat the casing be removed thereof. The body member is constructed forreceiving an end tube provided of a rod and being formed as integralpart of a guardrail tube. The end tube is blocked therein a cavity bythe rod sliding therein grooves, and for that the end tube be blockedthe guardrail tube is rotated vertically and fixed to the braces.

The same anchorage system is also used with a fastening device forconnecting a safety harness in a concrete slab.

The foregoing and other objects, features, and advantages of thisinvention will become more readily apparent from the following detaileddescription of a preferred embodiment with reference to the accompanyingdrawings, wherein the preferred embodiment of the invention is shown anddescribed, by way of examples. As will be realized, the invention iscapable of other and different embodiments, and its several details arecapable of modifications in various obvious respects, all withoutdeparting from the invention. Accordingly, the drawings and descriptionare to be regarded as illustrative in nature, and not as restrictive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and16, it is shown the body member including a recess (4), an end portion(3) being formed thereof locations (5) allowing to receive screws (16)fitting therewith for be fixed in a wood casing (15) before that theconcrete be poured therein and that the casing (15) be removed thereof,a cavity (1), and grooves (2).

The recess (4) receives an end tube (8) provided of a rod (10) and beingformed as integral part of a guardrail tube (6). The end tube (8) isblocked therein the cavity (1 ) by means of the rod (10) sliding thereinthe grooves (2), and for that the end tube (8) be blocked therein, theguardrail tube (6) is rotated vertically and fixed to the braces.

Further, the tube (6) is provided of metal pins (7) for fixing thebraces, a ring (11) for hanging construction elements, and a reinforcingplate (9) which is welded therebetween the tube (6) and the end tube(8).

Referring to the FIGS. 14, 15 and 16, it is shown the fastening devicefor connecting a safety harness, which includes a ring (12) welded to aplate (13) in which is introduced a tube (14) provided of a rod (18).

Referring to the FIGS. 17 to 18, it is shown the fastening device inoperation, and for that the fastening device be blocked therein, thedevice is rotated and screwed therein the end portion (3) by means ofthe plate (13) as shown to the FIG. 20.

Referring to the FIG. 19, it is shown the installation of the bodymember in a wood casing (15).

Referring to the FIG. 20, it is shown the installation of the fasteningdevice in a concrete slab (17).

Although only a single embodiment of the present invention has beendescribed and illustrated, the present invention is not limited to thefeatures of this embodiment, but includes all variations andmodifications within the scope of claims.
